Our List of The Best Infrared Thermometers [Updated]

If you’re looking for the best infrared thermometers, we have a detailed post laid out for you below. But first, let’s look at thermometers in general.

Whenever we come across the term ‘thermometer’ we think of those small devices that are placed in our mouth or on our forehead to measure body temperature. Such thermometers are used for medical purposes, and hence, are known as medical thermometers. Though these thermometers are highly effective in measuring the body’s temperature, they are not useful to measure the temperature of other surfaces or objects. It is because they have limited measurement range and are contact devices. 

But what if you have to measure the temperature of an object from a certain distance? It is impossible for medical thermometers to cater us in this regard. Hence, here comes the ultimate solution – Infrared (IR) Thermometers.

Infrared thermometers are devices that allow measuring the temperature of surfaces or objects from a distance. Whether it is plastic or metal, the IR thermometer can measure the temperature of all kinds of surfaces and objects.

How does an Infrared Thermometer work?

If you want to measure the temperature of a surface or an object without being in direct contact with it, then an infrared thermometer is your answer. Everything in this world radiates thermal energy. The thermal energy emitted by an object is directly proportional to its intrinsic temperature.

Infrared thermometers have detectors that transform this thermal energy into electronic signals that can then projected on a screen in less than a few seconds. Most infrared thermometers use a laser pointer to measure the exact temperature of a targeted object.

The high speed and excellent versatility make the infrared thermometer an essential product for numerous industrial, commercial, and home applications.

Uses of an Infrared Thermometer

There are situations when contact thermometers and probes may deliver more accurate results than their infrared equivalent. But there are certain situations where non-contact equipment is the best. Hence, Infrared thermometers are the best solution to measure the temperature of objects that cannot be touched, something that is too far away or too hot.

Hazardous objects

Numerous people working in the manufacturing, mining, or construction industry use infrared thermometers regularly. Because they frequently have to interact with hazardous objects, like electrical equipment, degreasing units, molten metal, and more.

Moving objects

An infrared thermometer finds its use in measuring the temperature of moving things. It includes items on a conveyor belt, specifically inside manufacturing plants. In addition to this, these are great tools to measure the temperature of living organisms like animals.

Food

You can also use an infrared thermometer to measure the temperature of food. Additionally, they can help to monitor those foods that risk contamination. For this reason, infrared thermometers are quite valuable tools for food manufacturers and health inspectors. Another use of these thermometers is to measure temperatures of foods not easily puncturable with the probes.

These thermometers are also highly useful in the house. You can use them for air conditioner ducts, check the surface of a grill, barbeque, and more.

Infrared thermometers are highly useful devices. So, if you too are looking for such a device then check the best-infrared thermometers right here.

Factors to Consider When Purchasing Infrared Thermometers

Features

There are different types of infrared thermometers available that have varying features. However, some features are common to most of them. An LCD screen display is an important feature where the temperature readings are displayed. In addition to this, the thermometer must have data logging abilities where it is possible to record the readings. The other feature is the ability to measure emissivity and laser sighting.

Purpose

Each infrared thermometer is designed for a specific purpose. Some are useful for medical purposes, some for industrial purposes, and some are used to determine the temperature of hot surfaces or objects at a distance. Hence, you must select an infrared thermometer based on your requirement.

Measurement Range

Even as there are different types of thermometers, so as their uses vary widely. From medical use to industrial applications, the temperature range you want depends on what kind of thermometer you need. Generally, models have a range of at least -50 Degree Celsius to 380 Degree Celsius. However, there are professional-grade thermometers with a wider range of -50 to 750 Degree Celsius. Hence, you need to be clear about your requirement. There is no point going for a very high range thermometer if you only need one for your family.

Emissivity

Infrared thermometers can measure external temperatures. The emissivity is related to the reflectivity of the scanned surface. The infrared thermometers featuring a fixed emissivity of 0.95 is perfect for reading commonly available solid-surfaces such as walls, pipes, metal, and more.

Fixed emissivity can result in issues when scanning reflective objects like oily, glass, or liquids. Hence, it is best to buy professional-grade models offering variable emissivity. This is because they would allow you to calibrate a thermometer for every surface you scan, for the most precise readout.

Distance to Spot Ratio

It is the distance at which an infrared thermometer scan temperature from a one-inch area. For example, a thermometer with a 12:1 ratio implies that it scans a one-inch spot when held at a distance of 12 inches from the target surface. Pick a thermometer that can cater to your need in the best way.

Accuracy and Speed

All thermometers recommended in our list offer accurate and quick results. There are advanced thermometers available for professional use that offer accurate results due to adjustable emissivity and better IR sensors. You can pick an infrared thermometer based on the level of precision you require.

Price

Lastly, it is essential to consider the price of an infrared thermometer before buying it. But make sure you consider buying a thermometer that incorporates at least all the basic features. It is because only such a thermometer would be able to serve your needs.

Conclusion

If you are looking for a device with high accuracy in temperature readings, then an infrared thermometer is the best gadget for you. Such a thermometer offers fast measures from surfaces both distant and near. Also, they have the potential of offering two dimensional reading of big areas where the temperature may differ from one point to the other. An infrared thermometer offers effective functionality for both domestic and commercial use. Hence, pick an infrared thermometer from the above list that meets your purpose, and that fits perfectly well in your budget.
